Is Entity Framework 7.0 RTM release going to work with .NET Framework 4.5?
According to comments in issue 2443 EF 7.0 was supposed to support Mono which requires 4.5 version of framework.
Recent code changes suggest an upgrade to 4.5.1, is this going to stay that way?
EF.Relational now (RC2) requires .NET 4.5.1
The latest versions of Mono have updated to the Microsoft reference source, so compiling against 4.5.1 should work just fine on Mono now.

Hey I tried to install the latest .NET Framework 6.0.1 from the official Microsoft Website and it shows as installed inside the Visual Studio Installer but I am somehow not able to select it. Neither can I upgrade existing Applications to 6.0 nor create Applications with .NET Framework 6.0.
So i tried installing .NET Framework 5.0 instead but it has the excatly same issues.
The highest Version that I can choose is .NET Framework 4.8.
In case it is important I am on Windows 10 - 21H1 - 19044.1415.

Last version of .NET Framework is 4.8. Last version of .NET is .NET 6. They are not the same thing, .NET is a successor of .NET Core.
I am about to port a Windows forms application (dotnet 4.7x) to dotNet Core 5. The application uses LiteDB (all else is straight c# winforms stuff). Before starting I need to determine if LiteDB 5.10 will work with Core 5.0.
LiteDB 5.x is .NET Framework 4.5 and .NET Standard 2.0 compatible. You can work with LiteDB in any target framework that .NE TStantard 2.0 is compatible, like:
.NET 5
.NET Core 2+
.NET Framework 4.6.1
Mono 5.4
Xamarin.iOS 10.14
Xamarin.Mac 3.8
Xamarin.Android 8
UWP 10.0.16299
Unity 2018.1

Is it possible to set the .NET Framework version for a ScriptComponentProject?
Currently it defaults to .NET 4, but I want it to be .NET 4.6.1
I've looked on the documentation page for ScriptComponentProject (https://www.varigence.com/Documentation/Samples/Biml/Script+Component+Project), but without any luck.
Ah, I found the answer! You need to set the Target Framework Version in your script project:
https://www.varigence.com/Documentation/Language/Element/AstComponentScriptProjectNode
And I think the available values are these:
Unspecified
Unspecified .NET Framework Version
NetFX20
.NET Framework 2.0
NetFX30
.NET Framework 3.0
NetFX35
.NET Framework 3.5
NetFX40
.NET Framework 4.0
NetFX45
.NET Framework 4.5
NetFX451
.NET Framework 4.5.1
NetFX452
.NET Framework 4.5.2
NetFX46
.NET Framework 4.6
NetFX461
.NET Framework 4.6.1
Which can be found here: https://www.varigence.com/Documentation/Api/Enum/ScriptProjectTargetFrameworkVersion
If you are using BIMLExpress 5.0.6xxx, you have probably faced the same issue.
I opened the generated .dtsx package and found that the TargetFrameworkVersion node placed inside of a separate PropertyGroup node. After I had moved it out to the first PropertyGroup of the same arrayElement node, then reopened my package in Visual Studio again, issue was gone! So you can write a script to move TargetFrameworkVersion node into the proper place for now.
Varigence support team told me that a public preview release is coming late next week which will include a fix for that (+also VS2017 support!).
I wanted to ask whether the ILNumerics library for the .Net Framework 3.5 is available.
I can with my project where I would like to use the library has not upgrade on that .Net Framework 4 or 4.5.
ILNumerics is designed for .NET framework version 4.0. On mono at least version 2.10 is recommended (http://ilnumerics.net/specifications.html)
May I ask why you don't want to upgrade the .NET framework?
We're currently developing an application that is using EF Code first (EF June 2011 CTP).
My first question is: Is it worth trying to upgrade to use a later version of EF?
Secondly, if so, does anyone know the steps involved to upgrade - when I try to install the NuGet package for EF 5.0 - beta 2, I end up with issues as the target framework is still 4.2.
Many thanks,
James.
The CTP is long time dead with no other version coming because all that stuff is currently part of .NET 4.5 beta and EF 5.0 beta. You must upgrade to those two and the upgrade will consist of re-targeting application back to .NET 4.0 / .NET 4.5, removing all dependencies to your current EF version and re-adding those dependencies for .NET 4.5 / EF 5.0.
Some time ago I wrote a blog post on this: http://blog.3d-logic.com/2012/04/11/entity-framework-zombie-a-k-a-microsoft-entity-framework-june-2011-ctp/. There is a number of issues with CTP 4.2 because of technical challenges related to shipping a .NET Framework library out of the .NET Framework (like 4.2 target). Move to .NET Framework 4.5 that contains the same feature set as EF 4.2 + bug fixes and has a go-live license. Use EF 5.0 on top of it and you will be in a better world.
Thanks for all the responses.
My main issue is that we rely heavily on ENUMs in our implementation of 4.2 code first. I attempted to migrate the project to 4.5 but ENUMs are not supported, and there is also an issue with table per hierarchy (which is easy to fix). The next move will be to upgrade to VS11 and use 5.0 - but this is a big undertaking.
#jwsadler:
Enums are supported by core EF libraries released as part of .net Framework 4.5 (e.g. System.Data.Entity.dll). To make enums work with CodeFirst/DbContext you do need EF 5.0.0 package from NuGet (use Install-Package EntityFramework -pre (-pre is important)). You need VS 11 for this since Visual Studio 2010 cannot be used to create applications that target .NET Framework 4.5. Note that when installing the nuget package on Visual Studio 11 the target version of the .NET Framework set for the project is taken into account. If you target .NET Framework 4 you will not be able to use EF5 features like enums or spatial.
